How To Update Samsung Galaxy GIO with CM9 Beta 7 Android 4.0 ICS Custom ROM

After Beta 6, here comes the latest CM9 Beta build for the Samsung Galaxy GIO S5660. And if you still don’t have any idea about this new Beta build, well, it’s called Beta 7 and it will address the bugs that were previously spotted from the previous installment. Do keep in mind that this is a custom ROM and not the official Android 4.0 ICS version. But before you download the source file for CM9 Beta 7 Android 4.0 ICS, better consider the following reminders and precautions.

-> First and foremost, this custom ROM can only be applied to rooted phones. Therefore, you will need to root your Galaxy GIO smartphone. (Warning: Rooting can void the warranty of your phone.)

-> We are not liable for any damages that could happen to your handset. This is a beta firmware. You will eventually encounter some bugs or errors.

-> Backup your phone’s important data but do not do such via KIES. You have to create a backup for your call logs, phone contacts, music, videos, photos and SMS messages.

-> Check your phone’s battery. Make sure that its power level won’t go any lower than 80 percent. This is to avoid any power interruption during the update process.

-> Disable your computer’s Firewall, Anti-Virus and Security suites. Do the same for your smartphone.

-> Enable your phone’s USB Debugging mode. Do this by going to Settings > Applications > Development. Check the box next to the USB Debugging option.
